Supporting Information for: Supramolecular Organogels Based on Perylenetetracarboxylic Diimide Trimers Linked with Benzenetricarboxylate Chengguang Gao,a Lin Xue,b Yuhan Chen,a and Xiyou Li*,a a Key Laboratory of Colloid and Interface Chemistry of Ministry of Education, Department of Chemistry, Shandong University, Jinan, China 250100. b Environmental Protection Bureau of Laiwu City, Laiwu, China, 271100 1 Figure S1. (A) Absorption spectra of trimer 2 in chloroform (5 10-7 mol/L) at different temperatures. (B) Fluorescence quantum yields of timer 2 in chloroform (5 10-7 mol/L) at different temperatures. This figure shows that the temperature rising does not bring significant changes to the absorption and fluorescence spectra of trimer 2 in chloroform. 2 Figure S2. The absorption spectra of trimer 1 (a) (510-6 mol/L) and trimer 2 (310-6 mol/L) in chloroform at different temperatures. The spectra revealed that the aggregation of both trimer 1 and 2 in a relative more concentrated solution are reversible and can be broken at elevated temperatures. 3 Figure S3. Normalized concentration dependent absorption spectra of trimer 2 in chloroform. The inset shows the peak intensity ratio of A0-1 / A0-0. This figure revealed that the aggregation of timer 2 in chloroform is concentration dependent. 4 Figure S4. The fluorescence spectra and fluorescence quantum yields (inset) of trimer 1 (a) and 2 (b) in chloroform (5 10-6 mol/L) at different temperatures. This figure shows that the aggregation of both trimer 1 and 2 are temperature dependent. 5 Figure S5. Normalized absorption spectra of trimer 2 in MCH at different concentrations. It reveals that timer 2 can form stable aggregates in MCH at much diluted solution. 6 Figure S6. IR spectrum of the dried gel of trimer 2. The bands at about 3500 cm-1 suggest the presence of hydrogen bonding. 7
