Cross Linking of Gold Nanoparticles with Hexa-peri-hexabenzocoronene Derivatives
Abstract:The present investigation delineates the synthesis of hexa-peri-hexabenzocoronene capped gold nanoparticles. The coronene derivative has been synthesized by cyclotrimerisation of carbazole and thioanisole bearing alkyne to form 1,2,4-substituted isomer and coplanarised through a Scholl reaction. AuNP with 3–5 nm size and narrow distribution were synthesized using coronene derivative as the capping agent. The absorption and emission maximum of the coronene capped nanoparticles showed a hypsochromic shift of 10–15 nm as compared to the pristine coronene. The TEM images showed aggregated and well dispersed nanoparticles in which coronene molecules act as a bridge, leading to an inter particle distance of 1–2 nm.
