TL;DR: The results directly demonstrate that a change in the molecular dipole moments induced by intramolecular electron transfer can introduce a macroscopic polarization change in VT compounds.

TL;DR: It is evident from the reaction Gibbs energy calculation that the above irreversible cyclotrimerizations are highly exothermic; therefore establishing that the intramolecular alkyne cyclotimerization is a powerful route to strained cyclic molecular strips.

TL;DR: Flapping molecules (FLAP) as mentioned in this paper is a ratiometric viscosity-sensing fluorophore that shows polarity-independent dual fluorescence, based on a unique V-shaped-toplanar conformational change in the singlet excited state (S1), in which the flexible motion of an eight-membered ring plays an important role.

TL;DR: The molecule based on the bridged bis(imidazole dimer) unit should be a good candidate for multiphoton-gated optical materials and can be initiated even by incoherent continuous-wave light irradiation, indicating that this two-photon reaction is highly efficient.

TL;DR: A synthetic and crystal engineering strategy is devised that enables the selective synthesis of a [CrCo] heterometallic dinuclear complex with a polar crystal structure, wherein polarization changes stem from intramolecular charge transfer between Co and the ligand.
