    • The concentration prepared herein was lower than the CGC of 3TEOS, but we confirmed by SEM and TEM that the aggregate structure constructed in the sol phase is almost the same as that constructed in the gel phase.

    • note
    • The fluorescence spectra of 3a gel and 3TEOS aggregates after sol-gel polycondensation in benzene was carried out (Figure S11 in the Supporting Information). Upon excitation of the porphyrin unit at 518 nm, the fluorescence spectra of a homogeneous benzene solution of 3a gave a peak at 655.0 nm. In the 3a gel it shifts to longer wavelength (661.5 nm), indicating that this shifted peak stems from the porphyrin J-aggregate. Interestingly, the 3TEOS aggregate after sol-gel poly-condensation also gave a peak shifted to longer wavelength (659.0 nm), supporting that the porphyrin J-aggregate is still maintained in the organic-inorganic hybrid.

    • The "elastic" gel as reported herein was obtained only when we used TFA as a catalyst. When HCl was used, we obtained the more fragile gel.
