A novel soluble terephthalate-bridged ladderlike polymethylsiloxane was synthesized successfully by stepwise coupling polymerization in three steps, including hydrosilylation coupling, hydrolysis and polycondensation. The bis(3-methyldichlorosilylpropyl) terephthalate monomer was ยฎrst synthesized by

The synthesis of 4-amino-1,2,4-triazole linked porphyrin-chlorin dimer and porphyrin dimer is described. New cationic porphyrin dimers were synthesized via the alkylation of the nitrogen atoms of 4,4%-bipyridine and 1,2-di-(4-pyridyl)ethene by meso-monobromomethylporphyrin. These cationic bisporphyr
## Abstract A simple method has been used to synthesize four porphyrin azides with cores such as N~4~, N~3~S, N~2~SO and N~2~S~2~ in 60โ90โ% yields by treating the corresponding aminoporphyrins with __tert__โbutyl nitrite (__t__BuONO) and azidotrimethylsilane (TMSN~3~) in THF/CH~3~CN under mild rea

The synthesis of three novel porphyrins (that are models for mesoporphyrin) requires the synthesis of eight new pyrroles, one new alkyl-3-oxohexanoate and two new dipyrromethanes. The new porphyrin free bases have hydrophobic substitution patterns different from that in mesoporphyrin. We are seeking
