Abstract

An emissive organic–inorganic hybrid material is obtained by a cationic metathesis between a blue fluorescent tetraphenylethylene‐based salt: [TPEIm2]I2, and a red‐NIR phosphorescent octahedral molybdenum cluster compound: Cs2[Mo6I8(OCOC2F5)6]. As demonstrated by Single Crystal X‐Ray Diffraction, the hybrid [TPEIm2][Mo6I8(OCOC2F5)6] crystallizes as a 2:2 dimer and emits in the red‐NIR area. Its emission properties are studied in the solid state and once embedded in poly(methylmethacrylate) by steady state and time dependent photoluminescence spectroscopy. They are further compared to the case in which the two starting salts are directly integrated in the polymer matrix. Obtained nanocomposites show evanescent UV‐2A optical writing and reading behavior, with color contrasts depending on how emitters have been introduced. [ABSTRACT FROM AUTHOR]

Abstract

Emissive ionic supramolecular frameworks are designed by associating tetraphenylethylene‐based tetra‐cationic units and di‐anionic molybdenum or tetra‐anionic rhenium octahedral clusters. Obtained structures were characterized by single‐crystal X‐ray diffraction. The emission properties of the hybrids were investigated as dry powders or in various solvents by one photon and two photon absorption leading to a O2 concentration dependent luminescence color for the Mo based hybrid.

Abstract

Since the hydrostatic pressure resistance ability of class III flextensional transducer is usually poorer, we did some researches on the common hydrostatic pressure resistance ability of deep water transducer to improve it. The hydrostatic pressure resistance ability of class III flextensional transducer can be improved that the way of overflow fills the acoustic compliance tube. With the simulating calculation of class III flextensional transducer using finite element software, a transducer prototype was made and a fitness to the transducer of small size acoustic compliance tube was designed. The conclusion is that the hydrostatic pressure resistance ability of acoustic compliance tube is over 3MPa. The transducer has two resonance peak at 760Hz and 2000Hz, with TVR 115dB and 125.1dB. TVR should be over 113dB between 680Hz and 3000Hz. The transducer still can work normally with hydrostatic pressure of 3MPa. The results showed that the hydrostatic pressure resistance ability of overflow class III flextensional transducer which fills the acoustic compliance tube was improved, and the transducer had the high-power transmitting ability in board band of frequencies.

Abstract

In order to study the radiation characteristics of the Saucer-Shape transducer, the vibration mode and electro-acoustic performance of the transducer were simulated and analyzed by using finite element software, and a transducer prototype was designed and manufactured. The measured results show that within the frequency band of 1.5~3kHz, the transmission voltage response fluctuation is less than 3dB, the source level is more than 196dB, the source level at the resonance point is more than 200dB, and the hydrostatic pressure resistance is more than 5MPa. The results show that the Saucer-Shape transducer not only has wide working band but also enables large transmitting power.
