A novel 'picket-fence' porphyrin, 5,10,15,20-tetrakisporphyrin (H2L) with ligating tetrahydrothiophene rings disposed perpendicular to the porphyrin plane has been synthesised.Its zinc(II) derivative, , binds two silver(I) ions co-operatively with a dissociation constant of 4.8 x 10-8 dm3 mol-1.Time-resolved fluorescence lifetime measurements reveal the presence of intramolecular photoexcited electron transfer in this donor-acceptor system.
