Abstract: The present invention addresses the problem of providing a luminescent labeling material for pathological diagnosis and luminescent nanoparticles for enabling high-sensitivity imaging that can avoid the negative impact of auto-fluorescence of cells on bioimaging. Provided are luminescent nanoparticles containing a luminescent dye, wherein the luminescent dye is a compound having a specific structure represented by Formula (1), and the luminescent nanoparticles have at least one of delayed luminesence or long Stokes shift luminescence.

Abstract: A communication apparatus is provided in a redundant communication system including a plurality of communication apparatuses having mutually-redundant configurations, and is configured so that its operating mode can be switched between a plurality of modes including an active mode and a standby mode. The communication apparatus includes a synchronization control unit configured to share client identification information with another communication apparatus included in the redundant communication system, and an address acquisition unit configured to acquire, in response to switching of the operating mode to the active mode, an IP address from a DHCP server by using the client identification information.

Abstract: Disclosed is a ?-conjugated compound that has a structure of the following Formula (1) and a HOMO level of ?5.3 eV or higher, in the formula, M represents CX1 or a nitrogen atom, X1 to X6 each represent an aromatic substituent or an aromatic heterocyclic group, in which at least four of X1 to X6 are electron-donating condensed aromatic ring substituents with 14 or more n electrons, and at least one of X1 to X6 is an electron-attracting substituent, and X1 to X6 may each independently further have a substituent.
