“…To corroborate the aggregation phenomena, a comparison of UV‐Vis and emission spectra in the presence and absence of trifluoroacetic acid (TFA) was carried out since it is known that TFA is used to break aggregation [31–34] . For this purpose, 30 μL of TFA were added in 10 mL of 10 −3 M solutions of derivative 1 .…”

“…To corroborate the aggregation phenomena, a comparison of UV-Vis and emission spectra in the presence and absence of trifluoroacetic acid (TFA) was carried out since it is known that TFA is used to break aggregation. [31][32][33][34] For this purpose, 30 μL of TFA were added in 10 mL of 10 À 3 M solutions of derivative 1. In the absorption spectrum, we can observe the change in the ICT band at the lowest energy in presence of TFA probably because of the triphenylamine group protonation that breaks the aggregation (Figure S7).…”

In order to achieve a multifunctional compound with potential application in organic photonics and electronics, a multidonor benzothiadiazole derivative was rationally designed and synthesized employing microwave irradiation as energy source, increasing the process efficiency about yields and reaction times in comparison with conventional conditions. This powerful compound displayed solvatochromism and showed efficient behavior as red optical waveguide with low OLC around 10‐2 dB μm‐1 and with the capacity of light transmission in two directions. In addition, the proposed derivative acted as efficient p‐type semiconductor in organic field‐effect transistors (OFETs) with hole mobilities up 10‐1 cm2V‐1s‐1. This corroborates its multifunctional character, thus making it a potential candidate to be applied in hybrid organic field‐effect optical waveguides (OFEWs).

“…Stimuli responsive luminescent materials have attracted much attention in recent years due to their potential application in optical storage [ 1 ], optoelectronic devices [ 2 , 3 , 4 ], security papers [ 5 ], and sensor [ 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 ]. The emission colors and intensities of these materials can be tuned by external stimuli, such as heat [ 16 , 17 , 18 ], solvent vapor [ 19 , 20 , 21 ], and mechanical perturbation (including grinding, shearing, smashing, or stretching) [ 22 , 23 , 24 , 25 , 26 ].…”

Construction of Luminogen Exhibiting Multicolored Emission Switching through Combination of Twisted Conjugation Core and Donor-Acceptor Units

Stimuli responsive luminescent materials, especially those exhibiting multicolor emission switching, have potential application in sensor, optical recording, security ink, and anti-counterfeit label. Through combination of twisted conjugation core and donor and acceptor units, a luminogen (2-(bis(4-(carbazol-9-yl)phenyl)methylene)malononitrile (1) was synthesized. Luminogen 1 can form three kinds of crystals emitting green (1GC, λem = 506 nm, ΦF = 19.8%), yellow-green (1YC, λem = 537 nm, ΦF = 17.8%), and orange (1OC, λem = 585 nm, ΦF = 30.0%) light upon 365 nm UV illumination. The emission of amorphous solid of 1 (1Am) overlaps with that of 1OC (λem = 585 nm), with quantum yield of 13.9%, which is seldom reported. Emission of 1 can be switched among green, yellow-green, and orange through morphology modulation upon exposure to thermal, solvent vapor, or mechanical stimuli. Finally, its potential application in optical recording was also investigated.
