This paper presents the preparation and characterization of a single-excitation, dual-emission ratiometric optical Li(+)-sensing device using a newly designed and synthesized highly Li(+)-selective fluoroionophore (KBL-01) carrying 14-crown-4 ether with tetramethyl and benzene blocking subunits as Li(+)-binding site and boron-dipyrromethene as fluorophore. The indicator dye was covalently immob...

Mineralocorticoid receptor (MR) antagonists, such as spironolactone (SPI) and eplerenone (EPL), are useful for treating hypertension and heart failure. However, these two agents have the serious side effect of hyperkalemia. We hypothesized that adding the ability to inhibit carbonic anhydrase (CA) would reduce the risk of hyperkalemia associated with MR antagonists. We investigated the profiles...

We explore theoretically the controls on dissolution of salt A, in an under-saturated brine of salts A and B. We show that, as the concentration of B increases, the dissolution rate of A decreases, for brine of given temperature. We also show that there is a sharper decrease in dissolution rate with increasing concentration, for concentrations of B above a critical value, where B limits the equ...

The title compound, C26H24BF2N3O, comprises a boron-dipyrromethene (BODIPY) framework and a phenolic Schiff base substituent group. The BODIPY unit is close to planar [maximum deviation from the least-squares plane = 0.040 (3) Å], and forms a dihedral angle of 80.38 (13)° with the meso-substituent phenyl ring and an angle of 56.57 (13)° with the phenolic ring in the extended substituent chain. ...

We disclose two novel BODIPY dyes, which contain the bulky substituent, [(4-dimesitylboryl)phenyl]ethynyl at 2- and 2,6-positions. The steric bulkiness of the boryl group is effective to suppress the intermolecular interaction in the solid state and thus these two compounds display intense fluorescence not only in solution but also in the solid state. In addition, the BODIPY dyes display sensit...

The title compound, C(17)H(15)BN(2)S, is one member in a series of diaza-borinanes featuring substitution at the 1-, 2- and 3-positions in the nitro-gen-boron heterocycle. The dihedral angle between the mean planes of the naphthalene and phenyl ring systems is 19.86 (6)°. In the crystal structure, two C-H⋯π inter-actions link the mol-ecules into sheets which lie parallel to the bc plane. There ...

The thermal environment of a crop is one the prime factors enhancing growth and production by regulating its physiological processes at different phenophases. To study impact regime on spring–summer-grown black gram (variety Pant Urd 31), an experiment was conducted with sowing dates (from first to third week March), soil application cobalt (Co) foliar sprays potassium (K) boron (B) in various ...
