Synthesis and structure of [C6N4H20]0.5[B5O6(OH)4]: A new organically templated pentaborate with white-light-emission

Synthesis, Structure, Property of a Templated Borate [Hdmpip][B5O6(OH)4]

“…It led to more charges being delocalized on B-O bonds, which is directly related to the electric dipole of hypersensitive transition and environmental of luminescent centers [33]. The probability of electric transfer from 2p state of O 2-to 3s state of B 3? are increased that has resulted in tunable emission peaks from A to E samples with exhibiting a red shift [12,17,18], which is consist with the previous reports. As shown in Fig.…”

“…The PL property makes the title compound to be a potential candidate for using in the preparation of phosphors for LED. This work also provides theoretic evidence for elucidating similare PL phenomenon of other templated borates [12,13,17,18].…”

“…The samples B, C and D were put in the Al 2 O 3 crucible, and annealed to reported previously [7][8][9][10][11][12][13][14][15][16][17][18] (Fig. 1b, c).…”

“…Boron is of particular interest because boron atom can coordinate with oxygen atoms not only in four-fold coordination (tetrahedron, BO 4 ) but also in threefold coordination (triangular, BO 3 ). Borate materials templated by various organic amines and transition metal complex have been extensively studied, including isolated rings [7][8][9][10][11][12][13], infinite chains [14], sheets [15,16], and networks [17,18]. The combination of templates and inorganic polyanions preserve the advantages of both organic and inorganic characteristics within a single molecular, may offer opportunities for generating a fantastic hybrid with unusual architectures and physical properties.…”

“…However, most of research about borate phosphors basically focuses on inorganic borates doped with rare earth metal ions, studies towards developing new templated borate phosphors have not well been explored. Until now, only limited reports about borate phosphors were revealed, (H 2 en) 2 (Hen) 2 B 16 O 27 [17,18] and [C 6 N 4 H 20 ] 0.5 Á [B 5 O 6 (OH) 4 ] [12] are revealed with tunable PL from green-blue to white by means of annealing treatment, and [C 6 H 16 N]Á[B 5 O 6 (OH) 4 ] is also revealed with different emission spectra in polar solvents [13]. From a structural viewpoint, the assembly of templates and boron-oxygen polyanions has resulted in the formation of a large number of the templated borates.…”
