Synthesis and crystal structure of a cumulenic quinoidal porphyrin dimer with strong electronic absorption in the infrared
Quinoidalization results in amazingly intense near-IR absorption in 1 (λ(max) = 1080 nm), whereas the shorter dimer 2 (λ(max) = 780 nm) is less conjugated because steric interactions force it into a contorted geometry. The crystal structure of 1 shows that the 62-atom chromophore is bow-shaped in th...
