Herein, zero-dimensional (C<small><sub>9<\/sub><\/small>H<small><sub>15<\/sub><\/small>N<small><sub>3<\/sub><\/small>)ZnCl<small><sub>4<\/sub><\/small>&nbsp;with space group&nbsp;<em>P<\/em>2<small><sub>1<\/sub><\/small>&nbsp;was synthesized for the first time. (C<small><sub>9<\/sub><\/small>H<small><sub>15<\/sub><\/small>N<small><sub>3<\/sub><\/small>)ZnCl<small><sub>4<\/sub><\/small>&nbsp;emits blue fluorescence at room temperature with external quantum efficiency as high as 42.5%, which are among the highest reported for Zn-based OIMHs, and it is comparable with the commercialized phosphors. Notably, the luminous integral intensity of (C<small><sub>9<\/sub><\/small>H<small><sub>15<\/sub><\/small>N<small><sub>3<\/sub><\/small>)ZnCl<small><sub>4<\/sub><\/small>&nbsp;at 470 K remains more than 50% of that at room temperature. Mn<small><sup>2+<\/sup><\/small>&nbsp;doping of (C<small><sub>9<\/sub><\/small>H<small><sub>15<\/sub><\/small>N<small><sub>3<\/sub><\/small>)ZnCl<small><sub>4<\/sub><\/small>&nbsp;was conducted to improve the photoluminescence. With increasing Mn<small><sup>2+<\/sup><\/small>&nbsp;concentration, the title compounds underwent fluorescence conversion from blue to green. The external quantum efficiencies of (C<small><sub>9<\/sub><\/small>H<small><sub>15<\/sub><\/small>N<small><sub>3<\/sub><\/small>)ZnCl<small><sub>4<\/sub><\/small>\u2006:\u20065%Mn<small><sup>2+<\/sup><\/small>&nbsp;and (C<small><sub>9<\/sub><\/small>H<small><sub>15<\/sub><\/small>N<small><sub>3<\/sub><\/small>)ZnCl<small><sub>4<\/sub><\/small>\u2006:\u200650%Mn<small><sup>2+<\/sup><\/small>&nbsp;were 43.7% and 42.9%, respectively. More importantly, (C<small><sub>9<\/sub><\/small>H<small><sub>15<\/sub><\/small>N<small><sub>3<\/sub><\/small>)ZnCl<small><sub>4<\/sub><\/small>\u2006:\u20065%Mn<small><sup>2+<\/sup><\/small>&nbsp;exhibited different luminous colors at different temperatures. As the temperature decreased from 290 to 110 K, the luminous color changed from green to light blue. Finally, a composite film was prepared to demonstrate the temperature response of this material, and the absolute sensitivity reaches 0.57%\/K. These findings fill in the gaps for low-temperature indication and expand the application scenarios of OIMHs.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>J. Mater. Chem.
