The monophthalocyanine complexes of samarium and terbium containing axial 2-mercaptobenzothiazole（Pc Sm（MBT）（1））, 2-（2-benzoxazol-2-yl） phenolate（Pc Tb（OON）（2）） or 2-（2-benzothiazol-2-yl）phenolate（Pc Tb（SON）（3）） ligands were synthesized and identified by elemental, LDI-TOF and X-ray（for 1） ***（PL） and electroluminescence（EL） spectra of the compounds contained only emission bands of phthalocyanine and axial ligands but did not contain the bands of f-f *** was found that among the complexes 1, 2, 3 the latter had highest photoconductivity（~10–7 S/cm） and photovoltaic *** organic photovoltaic device（OPv） of configuration of ITO/3/C60/Alq3/Al revealed open-circuit voltage（vOC） of 0.24 v and short current density（ISC） of 0.3 μA/cm2 under illumination by a xenon lamp at 17 m W/cm2.

Until recently the time period 2400-2200 Ma in the Erath history was characterized by low amount of age data for igneous events,and was even considered as‘magmatic age gap’(Condie et al,2009;Eriksson and Condie,2014).
