Uses

Used in Laser Applications:
Coumarin 30 is used as a laser dye for both pulsed and continuous wave (CW) operations, taking advantage of its high fluorescence yield and stability.
Used in Semiconductor Fabrication:
C30 can form a thin film on p-silicon (p-Si) semiconductor, which is utilized in the fabrication of aluminum/C30/p-Si based diodes, enhancing the performance and efficiency of these devices.
Used in Research and Development:
Coumarin 30 serves as a donor in the study of time-resolved fluorescence resonance energy transfer (FRET) when paired with fluorescein as an acceptor, providing valuable insights into molecular interactions and dynamics in various research applications.

Concise synthesis and fluorescent properties of coumarin-30 and its isomer 7-(diethylamino)-4-(1-methyl-1H-benzimidazol-2-yl)coumarin

Coumarin-30 and its regioisomer 7-(diethylamino)-4-(1-methyl-1H-benzimidazol-2-yl)coumarin were synthesised utilising condensation of the corresponding formylcoumarin with N-methylphenylene-1,2-diamine as the key step. Furthermore, absorption and fluorescence emission spectra of the two coumarins were recorded.

A secondary battery pack

PROBLEM TO BE SOLVED: To provide a secondary battery pack capable of securing its safety even though an electrolyte is leaked out from a secondary battery. SOLUTION: The secondary battery pack 20 houses a battery pack 11, in which 7 sets of secondary batteries 4 are arranged like stacked straw bags of two steps of upper and lower sides and a series of spot welding is applied on a metal cap of the secondary battery, or a battery case bottom and metal connection plates 5, 6 served as one electrode, in an insulation case 12 formed by a deep insulation lower case 3 and a deep insulation upper case 2. Therefore, even though the electrolyte is leaked out from the secondary battery 4 forming the battery pack 11, leakage of the electrolyte to the outside can be prevented.
