摘要： A reader includes: a transmission device that repeatedly transmits, at a cycle corresponding to the code length of a prescribed code string, an electromagnetic wave that is phase-adjusted with the prescribed code string; a reception device that receives the reflected wave from the object to be identified, cyclically overlaps a reception signal relating to the reflected wave at the cycle of the code length, and calculates the correlation value of the overlapped result and the prescribed code string; and a control device that controls the transmission device and varies the transmission frequency of the electromagnetic wave in a steplike manner to perform a frequency sweep within a prescribed frequency band, controls the reception device, causing the reception device to calculate the correlation value for each transmission frequency, and specifies the attributes of the object to be identified on the basis of the correlation value for each transmission frequency.

摘要： In order to provide a novel π-conjugated compound capable of increasing the light-emission efficiency of an organic electroluminescence element, for example, this π-conjugated compound has a structure indicated by general formula (1). (In general formula (1): Z1-Z6 each independently indicate a hydrogen atom, a deuterium atom, an electron-donating group D, or an electron-withdrawing group A; at least out of two among Z1-Z6 is an electron-donating group D and the other is an electron-withdrawing group A; and at least one ortho position combination Z1 and Z2, Z2 and Z3, Z3 and Z4, Z4 and Z5, Z5 and Z6, or Z6 and Z1 among Z1-Z6 is one combination out of an electron-donating group D and an electron-donating group D, an electron-withdrawing group A and an electron-withdrawing group A, or an electron-donating group D and an electron-withdrawing group A.)

摘要： A luminescent film includes a host compound, a blue phosphorescent compound, and a blue fluorescent compound, in which an emission spectrum of the blue phosphorescent compound and an absorption spectrum of the blue fluorescent compound have portions overlapping with each other; shortest wavelength-side maximum emission wavelengths of the blue phosphorescent compound (abbreviated as “BPM” in the expression) and the blue fluorescent compound (abbreviated as “BFM” in the expression) satisfy the following expression (1): λBFM≥λBPM: expression (1) in which λBFM represents the shortest wavelength-side maximum emission wavelength of the blue fluorescent compound and λBPM represents the shortest wavelength-side maximum emission wavelength of the blue phosphorescent compound; and light emission derived from the blue fluorescent compound is detected.

摘要： An organic electroluminescent device contains an anode, a cathode, and an organic layer containing at least one luminous layer. The organic layer is disposed between the anode and the cathode. At least one luminous layer contains a π-conjugated compound exhibiting no overlap between the electron density distributions of the HOMO and the LUMO in the molecule, such that electron transition between the HOMO and the LUMO occurs by a through-space interaction in the molecule. The π-conjugated compound has a π-conjugated aromatic ring at a moiety on which at least one of the HOMO and the LUMO is localized.
