Insolubility of functional molecules caused by polymorphism sometimes poses limitations for their solution‐based processing. Such a situation can also occur in the preparation processes supramolecular polymers formed solution. An effective strategy to address this issue is prepare amorphous solid states introducing “coformer” molecule capable inhibiting formation an insoluble polymorph through ...

We have explored the electronic transport properties of porphyrin-ethyne-benzene conjugates using an ab initio method. The results indicate that these ethyne-bridged phenyl porphyrin molecules can be used as candidates for molecular switching devices. The coplanar conformation of phenyl and porphyrin moieties allows a far larger current than the perpendicular conformation due to the near vanish...

To further investigate the influence of dye architecture on dye-sensitized solar cell (DSSC) performance, some near-infrared absorbing quinoline-based squaraine dyes (4a, 4b, and 4c) with different conjugated degrees carrying carboxylic or sulfonic groups as anchoring groups were designed, prepared, and applied as sensitizers in solar cells. The photophysical and photochemical studies showed th...
