Anisotropic self-assembly of photoluminescent oligo(p-Phenylenevinylene) derivatives in liquid crystals: An effective strategy for the macroscopic alignment of pi-gels

Hirai, Y; Santhosh Babu, S; Praveen, V K; Yasuda, T; Ajayaghosh, A; Kato, T (Wiley, 2009)

Aligned photoluminescent fibers are formed by the self assembly of an oligo(p-phenylenevinylene) derivative (OPV) in oriented liquid crystals (see figure). The aligned fibers of OPV show polarized yellow emission in the ...
Attogram sensing of trinitrotoluene with a self-assembled molecular gelator

Kartha, K K; Santhosh Babu, S; Srinivasan, S; Ajayaghosh, A (American Chemical Society, 2012-03-14)

Detection of explosives is of utmost importance due to the threat to human security as a result of illegal transport and terrorist activities. Trinitrotoluene (TNT) is a widely used explosive in landmines and military ...
Effect of the bulkiness of the end functional amide groups on the optical, gelation, and morphological properties of oligo(p-phenylenevinylene) pi-gelators

Santhosh Babu, S; Praveen, V K; Kartha, K K; Mahesh, S; Ajayaghosh, A (Wiley, 2014)

Herein, we describe the role of end functional groups in the self-assembly of amide-functionalized oligo(p-phenylenevinylene) (OPV) gelators with different end-groups. The interplay between hydrogen-bonding and pi-stacking ...
Functional pi-gelators and their applications

Santhosh Babu, S; Praveen, V K; Ajayaghosh, A (American Chemical Society, 2014)

One of the promising applications of pi-gelators is in organic electronics. Fluorescence of pi- gelators is another property that has great potential to be tapped for application in sensing and imaging. Anisotropic physical ...
Self-Assembled gelators for organic electronics

Santhosh Babu, S; Prasanthkumar, S; Ajayaghosh, A (Wiley, 2012)

Nature excels at engineering materials by using the principles of chemical synthesis and molecular self-assembly with the help of noncovalent forces. Learning from these phenomena, scientists have been able to create a ...
Self-location of acceptors as "isolated" or "stacked" energy traps in a supramolecular donor self-assembly: A strategy to wavelength tunable FRET emission

Ajayaghosh, A; Vijayakumar, C; Praveen, V K; Santhosh Babu, S; Reji Varghese (American Chemical Society, 2006)
Solvent-directed self-assembly of pi gelators to hierarchical macroporous structures and aligned fiber bundles

Santhosh Babu, S; Mahesh, S; Kartha, K K; Ajayaghosh, A (Wiley, 2009)

Morphology variation: The Boc-alanine linked OPV exhibits an unprecedented formation of periodic macroporous honeycomb structures in chloroform and aligned fiber bundles in toluene (see SEM images). This represents a unique ...
Solvent-Free luminescent organic liquids

Santhosh Babu, S; Aimi, J; Ozawa, H; Shirahata, N; Saeki, A; Seki, S; Ajayaghosh, A; Mohwald, H; Nakanishi, T (Wiley, 2012)
