Reaction mechanism, morphology, and fluorescence behavior of M1 + Zn(OTf)2 and TBAOH. (A) Cartoon representations of the reaction mechanism between [M1·Zn(OTf)2]n (2.00 mM) and 20.0 equiv. of TBAOH (5.00 mM), both in DMF/H2O (1/4, vol/vol). (B) SEM image, (C) AFM image, and (D) LSCM image of M1 + Zn(OTf)2 in DMF/H2O (1/4, vol/vol) before and after the addition of TBAOH. (E) Normalized fluorescent spectra of M1 + Zn(OTf)2 (2.00 mM) and a mixture M1 + Zn(OTf)2 (2.00 mM) and TBAOH (5.00 mM) at 298 K. λex = 410 nm. (Inset) Photographs of M1 + Zn(OTf)2 in DMF/H2O (1/4, vol/vol) before and after the addition of TBAOH recorded under a hand-held UV lamp. Slit: 10/15. (Scale bars: B, 20.0 μm; C, 20.0 μm; D, 100 μm.)
