About the Conference

Over the years, research on liquid crystals (LCs) has produced significant advancements in the understanding of supramolecular self-assembly and related technological applications. The discovery of liquid crystal displays and their commercialisation made the field more vibrant and multiplied the efforts of the scientific community in the quest for new materials with interesting properties. Understanding the structure–property correlations in LCs is a very important area for translating scientific findings into applications, and it requires a truly interdisciplinary effort.

This special state of matter — a combination of order and mobility intermediate to solids and liquids — is extremely sensitive to external stimuli such as temperature, pressure, light, and electrical and magnetic fields. Chemically, LCs may be organic, organometallic or inorganic in nature, and are broadly classified as thermotropic and lyotropic depending on the stimulus that brings about the phase transitions. A thermotropic LC is typically made up of two components: a rigid core and flexible chains connected to that core through different linking groups.

While the general concept of stabilising a liquid crystal was based on rod-like (calamitic) anisotropic molecules, in 1977 S. Chandrasekhar and co-workers showed that disc-like (discotic) molecules can also exhibit liquid crystalline phases — a discovery that motivated researchers to venture into many unexplored frontiers. The discovery of polycatenars, banana-shaped LCs, dendrimeric LCs, polymeric LCs and many other unconventional shapes followed.

Calamitic LCs have already marked their relevance and impact by supporting the billion-dollar display industry, while the corresponding story for discotic liquid crystals (DLCs) is a work in progress with huge potential, particularly in the area of organic electronics. This international conference provides a platform for all researchers working on discotic liquid crystals and their applications, at a very special moment in time — the 50th anniversary of DLCs.

What You Will Gain

  • A dedicated platform for researchers working on discotic liquid crystals and their applications.
  • Direct interaction between research students and scientists of international repute.
  • A consolidated view of five decades of progress, from molecular design to device applications.
  • Opportunities for new national and international research collaborations.

Reaching Guwahati

By Air

Lokpriya Gopinath Bordoloi International Airport (GAU), Guwahati, is about 20 km from the IIT Guwahati campus — roughly a 40-minute drive — and is well connected to Delhi, Kolkata, Mumbai, Bengaluru and Chennai, with international connections via Delhi and Kolkata. A pre-paid taxi counter is available in the arrival lounge, and app-based cabs serve the campus.

By Rail

Guwahati Railway Station (GHY) and Kamakhya Railway Station (KYQ) are the principal railheads, connected to all major Indian cities.

By Road

Taxis and app-based cabs are readily available from the airport and railway stations to the campus at Amingaon, North Guwahati.

Accommodation

On-campus accommodation is included in the registration fee for all categories except Research Scholars (without accommodation).

Delegates will be accommodated in the institute guest house and hostels, allocated according to category and availability. Accommodation is confirmed on a first-come, first-served basis, so early registration is strongly encouraged.

Accompanying persons and delegates preferring hotel accommodation in Guwahati city may make their own arrangements; a list of recommended hotels will be shared closer to the conference.

Check-in and check-out details will be circulated with the confirmation e-mail.

Visa Information

International delegates require a valid Indian visa. Participants should apply for a Conference Visa and must not travel on a tourist visa, as attendance at a conference is not permitted on that category.

Applications are made through the Indian Mission in your country or the Indian Government's official visa portal. Please apply well in advance, as conference visas require clearance and can take several weeks to process.

Registered delegates who need a formal invitation letter for their visa application may request one from the conference secretariat after registration is confirmed.
