The achievment of both high Tc (Curie temperature) and blue-white light in materials has always been a huge challenge that needs to be addressed urgently, especially in the approaching digital era led by flexible/wearable devices coupled with photoelectric features. However, this type of material has not yet been realized due to the limitations of both high Tc and flexibility. It is known that hybrid materials are superior to traditional inorganic films in super-flexibility, which has been fully demonstrated by the CH3NH3PbI3 films. Herein, we overcame this challenge and synthesized the first batch of high Tc dielectric phase transition bulk/film coupled with blue-white emission through an effective cation–anion regulation. At the same time, an ideal film forming ability and flexibility were also exhibited. Additionally, the switchable phase transition mechanism and significant photoluminescence characteristics of the hybrid compound [ASD]2[ZnBr4] (1, ASD = 5-azonia-spiro[4,5]decane) were analysed. Furthermore, it is especially noteworthy that 1 exhibited a unique and efficient broadband blue-white light emission with a photoluminescence quantum yield (PLQY) of 18.29%. In another words, this work sheds light on a new pathway towards desirable high Tc and flexible photoelectric multifunctional materials. [ABSTRACT FROM AUTHOR]

Psammosilene tunicoides is one of the main ingredients of the "Yunnan Baiyao". P. tunicoides is an endangered species included in the secondary protection list in China Plant Red Data Book as well as the endemic species in Southwest China. Its natural resources could not meet the needs of pharmaceutical production. Construction of core collection of P. tunicoides will lay the foundation for germplasm improvement and molecular breeding. The sequence variation of the key enzymes gene locus (β-AS) were carried out to survey the population structure and population history of the species. Among the 11 populations across its geographical range, 36 haplotypes were identified. The levels of haplotype diversity (Hd=0.905) were high, while the levels of population differentiation (GST=0.280) were low. Analysisof molecular variance (AMOVA) indicated that a significantly greater proportion of total genetic variationpartitioned among populations thanwithin populations (values of 77.43% and 22.57%, respectively). These results in combination with the star-like phylogenetic network analysis indicate that Hap1 as an ancestral haplotypewas shared in four populations, Hap2, Hap4, Hap15 and Hap16 are occurred in two populations, the remains as private haplotype only distributed in single population. The strategy of core collection was constructed in order to maximumpreserve genetic diversity of P. tunicoides., Competing Interests: The authors of this article and the planning committee members and staff have no relevant financial relationships with commercial interests to disclose., (Copyright© by the Chinese Pharmaceutical Association.)
