A phosphole-fused porphyrin dimer, as a representative of a new class of porphyrins with a phosphorus atom, was synthesized for the first time. The porphyrin dimer exhibits remarkably broadened absorption, indicating effective π-conjugation over the two porphyrins through the phosphole moiety. The porphyrin dimer possesses excellent electron-accepting character, which is comparable to that of a representative electron-accepting material, [60]PCBM. These results provide access to a new class of phosphorus-containing porphyrins with unique optoelectronic properties.

(Chemical Equation Presented) The rational, chromatography-free synthesis of two regioisomeric 5,10-diaryltripyrranes from pyrrole and aromatic acids has been developed. The strategy is general and should be applicable to a broad range of acids. This meth
Cycloaddition reaction of benzoheteroazepine: Synthesis of 4a,5,6,12-tetrahydro-1H-1,3-oxazino[3,2-d][1,5] benzothiazepin-1-ones and 1H,7H-1,3-oxazino[3,2-d][1,5] benzodiazepin-1-ones

2,3-Dihydro-1,5-benzothiazepines and 2,3-dihydro-1H-1,5-benzodiazepines reacted with α -carbonylketenes, generated from 2-diazo-1,3-diphenyl-1,3-propanedione and 2-diazo-1-phenyl-1,3-butandione by heating, to give [2+4] cycloadducts 4a,5,6,12-tetrahydro-1H-1,3-oxazinop[3,2-d] [1,5]-benzothiazepin-1-ones and 4a,5,6,12-tetrahydro-1H,7H-1,3-oxazino [3,2-d][1,5]-benzodiazepin-1-ones. The cycloaddition reactions showed different regioselectivities when different 1,5-benzoheteroazepines reacted with asymmetric 2-diazo-1-phenyl-1,3-butandione. The conformations of cycloadducts and cycloadducts reaction mechanism were described.
Stepwise syntheses of core-modified, meso-substituted porphyrins

Simple conditions are discovered to afford modified tripyrrin derivatives by condensation of 2,5-bis(α-hydroxymethyl)pyrrole, thiophene and furan derivatives with pyrrole in the presence of acid catalyst. The core-modified porphyrins were synthesized by acid catalyzed 3+1 condensation of modified tripyrrins with 2,5-bis(α-hydroxymethyl)-substituted pyrrole, thiophene or furan. This new process gives a single porphyrin isomer and overcomes the synthetic problems associated with separation and purification of regioisomeric mixtures.
