In the presence of l‐ethyl‐3‐(3‐dimethylaminopropyl)carbodiimide (EDC), the chemiluminescence (CL) intensities of poly(3, 4, 5‐trihydroxybenzoateester)dendrimers, 1 and 2 , having 1,2‐pyrocatechol and 1,3,5‐trihydroxybenzene as core molecules and also six and nine gallic acid units in the periphery, were respectively 7.4‐ and 2.4‐fold stronger than those of 1 and 2 in the absence of EDC. Similarly, the CL intensities of 1 and 2 in the presence of cetyltrimethylammonium bromide (CTAB) were respectively 4‐ and 1.7‐fold stronger than those of 1 and 2 in the absence of CTAB.
