With the flourishing development of emitting materials, tremendous technological progress has been accomplished. However, they still face great challenges in convenient economical environmental-friendly large-scale commercial production. Herein we designed this hybrid lead/rare earth-free crystals with the large size of 2.7*3.0 cm, an emerging class of high-efficiency luminescent material, (PYE)[Cu2I3] (1), which emits intense photoluminescence with a high emissive quantum yields of 32.11%. In addition, the results demonstrate that it is possible to obtain regulatable fluorescence intensity by introducing free groups in material design through simple molecular design. The dielectric constant curve remains relatively smooth before melting point. Therefore, it will be an important exploration and effective way for new material design to achieve artificial intelligence luminescent molecules, in this way, the personal customized application can be realized in display and sensing.

Potentiometric measurements have been obtained in order to examine the thermodynamic stability of copper(I) species and to study halide-complex formation in propylene carbonate in a 0.1 mol dm-3 tetraethylammonium perchlorate medium at 25 deg C.A value of 10-3.44 dm3 mol-1 has een found for the concentration constant, KD, of the disproportionation reaction:.In the halide system two mononuclear complexes CuX and CuX2(1-) are formed.The solubility products of CuX, pKsp, are 16.0, 15.8 and 17.9 and overall formation constants of CuX2(1-), logβ2 are 19.9, 17.9 and 17.2 for X=Cl(1-), Br(1-) and I(1-), respectively.The results are discussed in terms of solvation of the various complexes.
