Role of synergistic π–π stacking and X–H⋯ Cl (X= C, N, O) H-bonding interactions in gelation and gel phase crystallization
The self-assembly of p-pyridyl-ended oligo-p-phenylenevinylenes (OPVs) in ethanol leads
to the formation of either hollow or solid microrods. The corresponding protonated OPVs with …
