Summary: | Due to the well‐known optical limiting properties of indium (III) phthalocyanines (In [III] Pcs) and aiming at extending their conjugation system, a highly branched indium phthalocyanine polymer was prepared. Flash chromatography was used for obtaining a pure polymer of polydispersity index near to the unity. The structure of the prepared polymer was determined using different spectroscopic techniques. Optical limiting and open aperture Z‐scan measurements were carried out according standard procedures. Compared with many other phthalocyanines, the prepared indium‐phthalocyanine polymer shows a high optical limiting performance that is indicated by a relatively low limiting threshold of 430 mJ cm−2 and a large nonlinear absorption coefficient (α2 = 3.4 × 10−8 cmW−1).
