Two new emissive mononuclear copper（Ⅰ） triphenylphosphine complexes with functionalized 6-tert- butoxycarbonyl-2,2＇-bipyridiue chelating ligands were prepared and characterized. Each Cu（Ⅰ） cation has a markedly distorted P2N2 tetrahedral array with two different Cu--N bond distances, due to the addition of the bulky tert-butoxycarbonyl group at the 6-position of the 2,2＇-bipyridyl ring. A weak low-energy broad absorption band appears at 330-500 nm in their CH2Cl2 solutions, which is influenced by the methylation of the 2,2＇-bipyridyl ring. At room temperature, the photoluminescence can be clearly observed both in degassed CH2Cl2 solution and in the solid state, because of the introduction of the bulky tert-butoxycarbonyl substituent, and the emission properties are remarkably affected by both the methylation and the alkoxycarbonyl variation of the 2,2＇-bipyridyl ring. It is shown that the introduction of the bulky tert-butoxyearbonyl group is favorable for improving the emission properties of the 6-alkoxycarbonyl-2,2＇-bipyridine-based cuprous complexes.

Fluorescence detecting both organic and inorganic analytes has aroused tremendous scientific interests, because fluorescence techniques have high sensitivity and are easy to operate. A new threedimensional(3D) MOF {[(CH_(3))_(2)NH_(2)][Zn_(3)(bbip)(BTDI)1.5(OH)]·DMF·MeOH·3H_(2)O}n(JXUST-13, bbip = 2,6-bis(benzimidazol-1-yl)pyridine and H_(4)BTDI = 5,5-(benzo[c][1,2,5]thiadiazole-4,7-diyl)diisophthalic acid)with new 4,4,8-connceted topology has been successfully synthesized and structurally characterized. Importantly, JXUST-13 could recognize H_(2)PO_(4)-and acetylacetone(Acac) by obvious fluorescence blue shift and slight enhancement with the detection limits of 2.70 μmol/L and 0.21 mmol/L, respectively. In addition, JXUST-13 exhibits relatively good thermal stability, chemical stabilities as well as reusability, and the analytes could be distinguished by naked eye and fluorescence test paper. Remarkably, JXUST-13 is the first dual-responsive MOF sensor based on fluorescence blue shift for the detection of H_(2)PO_(4)-and Acac with good selectivity in a handy, economic, and environmentally friendly manner.

在加快我国产业结构调整,促进区域经济协调发展的过程中,在我国产业转移被寄予厚望的同时,我们还须清醒地认识到其中经济风险的潜藏与现实存在。对经济风险的全面评估,须从经济和社会两方面分别考察产业转移中的经济福利风险和社会福利风险,然后根据不同经济发展阶段的要求赋予相应的权数,科学评估我国产业转移中经济风险水平。实证分析了江苏省13个地级市在产业转移中现实的经济风险状态,并提出相应政策建议,以期为江苏省制定和实施产业政策、实现风险管理提供有益思路与方法。

国际海运业风险大、周期长,其高质量发展离不开国家政策的支持。国际经验表明,对国际海运业实施吨税(Tonnage Tax)可以提升本国船舶运力,促进其发展。基于1994-2021年《海运业年度审查报告》统计的拥有吨位在世界前列的24个国家相关数据,运用多期双重差分模型实证检验吨税对国际海运业的具体影响后发现,实施吨税可以吸引船舶在本国进行登记,提升悬挂本国国旗的吨位占比以及增加船舶吨位,提高本国国际海运业的竞争力。异质性分析表明,吨税制度对税负水平较高国家的影响大于税负水平较低的国家,对非欧洲国家的影响大于欧洲国家。我国应适时引入吨税,为国际海运业提供良好的营商环境。我国吨税设计宜采用荷兰模式,明确只有国际海运以及与其直接相关的辅助活动才能适用,设置合理的锁定期,允许国际海运企业自行选择适用吨税或是企业所得税。
