Thin films of ZnTPP are developed on glass substrate by means of thermal vapor deposition technique. Substituted derivatives of porphine are called porphyrins. Many porphyrins are found in nature with the dominant example being protoporphyrin IX. Many synthetic porphyrins are also known, including octaethylporphyrin and tetraphenylporphyrin. • Common porphyrins
