The electronic excited states of molecular aggregates and their photophysical signatures
have long fascinated spectroscopists and theoreticians alike since the advent of Frenkel …

This tutorial review summarizes recent progress in the design, synthesis, and multifunctional
properties of fully conjugated macrocyclic π-systems. We focus on the π-expanded …

The primary questions motivating this report are: Are there ways to increase coherence and
delocalization of excitation among many molecules at moderate electronic coupling …

Excess electron generation through doping with alkali and superalkali metals is well known
to enhance NLO responses. On the contrary, superhalogen doping is an unexplored …

Progress in organic synthesis opens exploration of a rich diversity of molecules with
interesting new structural topologies. This is the case of a recently synthesized helically …

V-Shaped porphyrin dimers, with masked p-phenylene bridges, undergo efficient oxidative
coupling to form meso–meso linked cyclic porphyrin oligomers. Reductive aromatization …

The effect of the length of pendant side chains in centrosymmetric quadrupolar molecules on
dynamics of their most perplexing photophysical phenomenon, ie, symmetry-breaking …

π-Conjugated oligothiophene is considered a chain segment of its polymeric counterpart,
whose size and shape can be precisely controlled. Because of its simplified structure, it is …

Conjugated molecules with phenylethynyl building blocks are usually characterised by
torsional disorder at room temperature. They are much more rigid in the electronic excited …

Ultrafast structural relaxation of photoexcited 2, 2′: 5′, 2 ″: 5 ″, 2‴-quaterthiophene (4T)
and 3, 3‴-Dihexyl-2, 2′: 5′, 2 ″: 5 ″, 2‴-quaterthiophene (DH4T) in solution were …
