Synthesis and properties of porphyrin-expanded porphyrin click dyads pp 7943e7949
Yogita Pareek, Mangalampalli Ravikanth*
Six covalently linked triazole bridged porphyrin-expanded porphyrin dyads containing Zn(II) porphyrin as energy donor and thiarubyrin, oxasmar-agdyrin and BF2eoxasmaragdyrin as energy acceptors were synthesized under click reaction conditions and studied their absorption, electrochemicaland photophysical properties.
