This work illustrates how minor structural perturbations produced by methylation of 4′-(dodecyloxy)-4-cyanobiphenyl leads to enthalpy-entropy compensation for their melting processes, a trend which can be analyzed within the frame of a simple intermolecular cohesive model. The transformation of the melting thermodynamic parameters collected at variable temperatures into cohesive free-energy densities expressed at a common reference temperature results in a novel linear correlation, from which melting temperatures can be simply predicted from molecular volumes. In tune with temperature! The transformation of the melting thermodynamic parameters into cohesive free-energy densities (CFED) for 4′-(n-oxy)-i′-methyl-j-methyl-4-cyanobiphenyl (CnLi′,j) provides a novel linear correlation for predicting melting temperatures in a simple way.

Three novel AuI polyynes have been prepared in high yield by copolymerization between an AuI complex precursor and different ethynyl aromatic ligands. The investigation of their photophysical behavior has indicated that forming polyynes through polymerization not only maintains the high transparency of the corresponding AuI polyynes similar to those of their corresponding small molecular AuI acetylides, but also effectively enhances their triplet (T1) emission ability. Critically, owing to their enhanced T1 emission ability, all the AuI polyynes exhibit a stronger optical power limiting (OPL) ability against a 532 nm laser than the corresponding small molecular AuI acetylides. The AuI polyynes based on fluorene and triphenylamine ligands show even better OPL performance than the state-of-the-art OPL material C60, indicating their great potential in the field of laser protection. More importantly, in a prototype OPL device made by doping the fluorene-based AuI polyyne into a polystyrene (PS) solid matrix, substantially improved OPL activity has been observed compared with that in the solution, demonstrating its great potential for practical application. All these results have provided a new strategy to achieve a balance between high OPL activity and good transparency for OPL materials, representing a valuable attempt towards developing new OPL materials with high performance to cope with the key problems in the field of nonlinear optics.
