“…The hexadentate donor motif 81 utilizes amides rather than acetates to bind Hg 2+ or Cd 2+ , the PET-type signaling of which is monitored by conjugated (94)(95)(96) or tethered (97 and 98) fluorophores [96][97][98][99]. …”

“…Organic solid-state photoactive chromophores have received increasing attention during the past 20 years due to their unique optical properties and promising optoelectronic applications in the fields of lasers [1,2], sensors [3][4][5][6][7], and biological imaging [8][9][10]. Meanwhile, more and more research attention has been paid to molecule-based micro/nanomaterials in chemistry, materials science, and pharmaceutics/medicine [11][12][13][14], since micro/nanomaterials exhibit unique properties superior to those of their bulk counterparts [15,16], owing to their surface effect, quantum size effect [17,18], and so on.…”

The development of metallic fluorescent materials, -conjugated molecular systems with high-efficiency generation of blue light, and new ways to fabricate metallic/organic luminescent materials plays an important role in the fields of large-scale flat panel displays and soft optical devices. Herein, different fluorescent films have been fabricated by low vacuum physical vapor deposition method (LVPVDM), including single/two-component films. Compared with raw materials, all films show novel fluorescent behaviors, which means potential application in the fields of multicolor luminescence and thickness-optical response sensors. Meanwhile, the speculation is demonstrated in many ways that the maximum emission ( em max ) at 406 nm and 426 nm of pristine 2,6-naphthalenedicarboxylic acid (26NCA) is caused by the crystal structure, while the shoulder peak at 445 nm is caused by the self-structure of 26NCA molecule. Significantly, this speculation may afford new insight into the relationship between not only crystal structure and luminescence, but also molecular self-structure and luminescence, which means a new strategy to tune the fluorescent behaviors based on molecular self-structure by LVPVDM. Therefore, this work provides a facile way to fabricate single/multicomponent metallic/organic film materials with tunable blue luminescence properties, which have potential application in the fields of next generation of photofunctional materials.

“…Therefore, many fluorescent sensors for sensing metal ions (such as Zn(II) [7], Cd(II) [8], Cu(II) [9], Pb(II) [10], Hg(II) [11] and Cr(III) [12]) have been successfully designed and synthesized. Although some chromogenic sensor for Ni(II) ion have been reported [13], the fluorescent sensor for Ni(II) ions is extremely rare.…”

In this paper, a high selective fluorescent sensor for nickel ion based on borondipyrromethene (BODIPY) has been studied. Upon addition of Ni(II) ion, the fluorescence of sensor (compound 1) would be quenched, and the selectivity towards Ni(II) ion over Ag(I), Cd(II), Cu(II), Fe(III), Hg(II), Pb(II), and Zn(II) is good in acetonitrile, there is almost no interference from other heavy metal ions. The stoichiometry of complexation for compound 1 with Ni(II) ion is 1:1, and the quenching process could be reversed by triethanolamine. KEYWORDS
