摘要:
The application relates to compounds of the Chemical Formula 1 having improved infrared absorption properties. The compounds are useful for infrared absorbers, infrared (IR) absorbing/blocking films, photoelectric devices, image sensors, and electronic devices comprising the photoelectric devices or sensors.
摘要:
The invention provides near infrared absorbing materials showing high light-to-heat conversion efficiency and high sensitivity to lasers whose emission bands are within the range of 750 nm to 900 nm, original plates for direct printing plate making, and novel compounds which can be applied to such absorbing materials and plates. The compounds are polymethine compounds of the general formula (I) shown below, while the near infrared absorbing materials comprise the polymethine compounds. wherein R1 represents an alkoxy group which may be substituted; R2 represents an alkyl group which may be substituted; R3 and R4 each represents a lower alkyl group or R3 and R4 taken together represent a ring; X represents a hydrogen atom, a halogen atom or a substituted amino group; Y represents an alkoxy group which may be substituted or an alkyl group which may be substituted; Z represents a charge neutralizing ion.
摘要:
Photographisches Negativmaterial mit mindestens einer Schicht, die eine desensibilisierte Silberhalogenidemulsion enthält, wobei als Desensibilisator ein trinukleares Heptamethincyanin oder ein halogeniertes trinukleares Tetramethincyanin mit drei gleichen heterocyclischen Ringsystemen verwendet wird, die gegebenenfalls unterschiedlich substituiert sind und durch drei gleiche, gegebenenfalls mesomere Methinsysteme miteinander verbunden sind, eignet sich zur Verarbeitung bei gedämpftem Tageslicht, weist aber dennoch bei intensiver Belichtung eine genügende Empfindlichkeit auf.
摘要:
Direktpositives photographisches Material mit mindestens einer Schicht, die eine auf chemischem Wege oder durch Belichtung oberflächenverschleierte Silberhalogenidemulsion und als Sensibilisator einen trinuklearen Tetramethincyaninfarbstoff enthält, in dem die Methinwasserstoffatome ganz oder teilweise durch Fluor-, Chlor-, Brom- oder Jodatome ersetzt sind. Die neuen trinuklearen Tetramethincyaninfarbstoffe verleihen den photographischen Materialien eine ausgezeichnete Blauempfindlichkeit. Ferner werden hohe Maximaldichten und sehr niedrige Minimaldichten erreicht.
摘要:
Disclosed are discrete PEGylated dyes, that is, dyes, generally ones that are fluorescent, but could also include chemi-luminescent or electrochemiluminescent and related dye or dye precursors, that have discrete PEG constructs chemically attached in various configurations on the dye, and in the entire range of constructs, discrete PEG compounds (polyethylene glycol oligomers that are made synthetically according to methods disclosed in U.S. Pat. No. 7,888,536 and US Pub. No. 2013/0052130). The dyes are modified in a range of ways to control or optimize the properties of water solubility, non-specific binding (in vitro), biodistribution (in vivo), cell internalization (non-cell or cell based assays in vitro, and in vivo diagnostics and therapy), as well as aggregation.
