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.

Figure S2. The absorption spectra of trimer 1 (a) (510-6 mol/L) and trimer 2
(310-6 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.

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.

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.

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.

Figure S6. IR spectrum of the dried gel of trimer 2. The bands at about 3500 cm-1
suggest the presence of hydrogen bonding.
